    Abstract: © A door operator with limit stop sensing means (51, 52), said operator comprising
    (a) A reversible electric motor (5) for driving the door between the opened and closed positions; (b) Drive means (99, 15; 315, 317, 307) connected with the reversible electric motor (5) and connectable with said door to effect such opening and closing; (c) Said drive means (99, 15; 315, 317, 307) including drive releasing means (21, 319) for releasing drive between said reversible electric motor (5) and said door to permit said door to be manually opened in the event of power failure, said limit stop sensing means (51, 52) comprising two driven type limit stop sensors (51, 52), one being for an «up» or open limit stop and the other being for a «down» or closed limit stop, characterised in that each of said limit stop sensors (51, 52) being zero setable and having respective switch means associated therewith which is only operable when either of said limit stop sensors (51, 52) are at the zero position, said respective stop limit sensors (51, 52) being connectable with said reversible electric motor (5) to switch off power to said reversible electric motor (5) when operated, whereby said limit stop sensors (51.52) may be zeroed to set the «up» and the «down» positions respectively, when drive from the motor to said garage door will stop.

    Inventor: SOMMER, Frank

    Abstract: The invention relates to a drive device for a sliding door (1), which drive device has a drive unit (3) mounted in a stationary manner and comprising a motor (8) and a pinion (7), and also a rack (6) fixed in a desired position on the sliding door (1). In order to actuate the sliding door (1), the pinion (7) is mounted in a working position in which the pinion (7) is in engagement with the rack (6). To install the rack (6) on the sliding door (1), the pinion (7) can be placed into an adjustment position located below the working position. In the adjustment position, a spacer sits at least on a subregion of the teeth of the pinion (7), with the outside of the spacer forming a sliding surface for the rack (6) and being at a distance from the centre of the pinion (7) that is matched to the difference in position of the pinion (7) in the working position and in the adjustment position. In order to set the desired position of the rack (6), the latter rests on the sliding surface of the spacer.
